Battery CCA Calculator
Determine minimum battery CCA for your vehicle.
CCA Reference by Engine
| Engine Type | Min CCA | Recommended |
|---|---|---|
| 4-Cyl Gas (2.0-2.5L) | 400-500 | 500-600 |
| 6-Cyl Gas (3.0-3.6L) | 500-600 | 600-700 |
| V8 Gas (5.0-6.2L) | 600-750 | 750-900 |
| 4-Cyl Diesel | 600-750 | 800-900 |
| 6-Cyl Diesel | 750-900 | 900-1000 |
| V8 Diesel | 900-1100 | 1000-1200 |
Understanding Battery Ratings
- CCA - Cold Cranking Amps at 0°F (-18°C)
- CA - Cranking Amps at 32°F (0°C), typically 25% higher than CCA
- RC - Reserve Capacity in minutes
- Ah - Amp Hours (deep cycle rating)
